How can i merge files into One file.files contain texts/lines/Images .So how can i merge the files. Please Help me. It is an Windows Application.

It really depends on what you want to do with them, how many you have, and so forth.
If you really want to combine any number of any files into a single file, then you probably should look at ZIPing them.
There is an article here which may help: C# Zip Files and/or Folders[^]

Thanks for reply. I applied the following code.but It does not work .why?Please tell me.
#region Merged Multiple Files
public static void mergefiles(string inputpath,string outputPath)
string[] tmpfiles = Directory.GetFiles(inputpath, "*.pcl");
using (StreamWriter writer = File.CreateText(outputPath))
foreach (string tempFile in tmpfiles)
using (StreamReader reader = File.OpenText(tempFile))
catch (Exception ex)
Program.WriteLog(ex.Message, ex.StackTrace);


#endregion Merged Multiple Files

It will work - but it won't do what you want it to.
While it will happily write all the files into one big file, it won't let you read them back again, because it doesn't include any code or markers, or directory to say where one ends and the next starts.
You need to either include that info, and the type of the file, and probably the file name, or use something that does include it. Like ZIP for example. :laugh:

Although I can see potential issues with your code it would be useful if you could expand on the reasons why it doesn't work.

Are you recieving errors, if so when (compilation errors, runtime errors) and what are those errors.

If no errors in what way is the output wrong? No output? output in unexpected format?
